The airplane used in the parachuting scene is a Grumman designed TBM Avenger. torpedo bomber built by General Motors. Thus the TBM designation which GM built 7,546. During WWII the three seat torpedo bomber concept became outdated due to increasingly effective anti-aircraft capabilities, so the Avengers were used as level bombers, anti submarine, reconnaissance, light transport or cargo work and medical evacuation. After WWII they were modified for Carrier Onboard Delivery. or COD.
